flowers all the season." The plants in the Arboretum, how- 

 ever, originally grown from seed collected by Dr. George 

 Engelmann in New Mexico, have flowers of a very pale lemon- 

 yellow or creamy-white color, and there is not the slightest 

 appearance which would give the suspicion that the blossoms 

 were ever rose-colored or pink, unless it is that a slightly rosy 

 tinge may be detected on the outer edge of the petals when 

 they are about to fall. It may be that the color in these plants 

 is abnormal, but it hardly seems probable. 



The fruit ripens in late autumn, it is light red in color and is 

 rather sparingly produced here. On account of its white flow- 

 ers and continuous blooming habit this Rose may prove to be 

 of much interest and value to hybridizers as soon as it becomes 

 well known and disseminated. 



Of the hardy wild Roses indigenous to the eastern part of 

 North America the species known as the Swamp Rose (/?. 

 Carolina) is one of the most familiar. 



It is the tallest-growing of our local species, as well as the 

 latest to flower, the rather small blossoms not appearing until 



stove would prove entirely satisfactory, my preference for the 

 larger being not only because it requires less attention, but 

 because it is also useful in the fall, when I screw on 200 

 feet of pipe to warm a Chrysanthemum shelter, at which time, 

 of course, the consumption of coal is largely above the winter 

 average. 



Among other methods of heating, the old tile flue seems to 

 be the best, and is no doubt good as long as the flue is tight. 

 There are numerous suggestions for heating with coal oil and 

 sketches of arrangements to make it efficient. Perhaps, for a 

 cold house, where an occasional fire is desired, coal oil may 

 answer as a makeshift, but in my experience coal oil is expen- 

 sive for a steady heat, and I have never found odorless oil or 

 smokeless stoves, and these latter require at all times great 

 care, and are unpleasant things to handle. A flue is necessary 

 to carry off products of combustion, and the slightest down- 

 draft will throw smoke into the house. 



Such a small plant-house has, of course, its limitations, and 

 will not hold many specimen plants, but will shelter more

the first or second week of July, or after the beauty of most 

 other wild Roses is past. In the shrubbery the flowers usually 

 appear in large corymbose clusters, and they are followed 

 by a profusion of bright red fruit, which retains its color 

 throughout the winter.

HPHE amount of coal consumed in any stove will vary some- 

 *■ what according to the judgment of the fireman, but firing 

 twice a' day a stove for the house described in an earlier article 

 will consume half a ton of coal a month, during ordinary winter 

 weather, in maintaining a sixty-degree Fahrenheit nighttemper- 

 ature. Where more frequent supervision is given and the cin- 

 ders utilized a saving on this amount of fuel can be made. 

 The small stove has a capacity for the consumption of a much 

 larger amount of fuel than this, so that in extreme weather its 

 heating capacity is quite up to the house of the size described. 

 My preference is for a larger stove which has a larger fire-pot, 

 and which, while burning slightly more coal, has a larger body 

 of fire and requires the minimum of attention. Such a stove 

 will burn steadily with closed drafts on a consumption of 1,200 

 pounds of coal a month. Probably in most cases the small 



plants than would seem credible. With a judicious selection 

 one may have a fair number of flowers at all seasons, espe- 

 cially if a supply of bulbs is potted up and held in reserve to be 

 brought on as required. As our piscatorial friends do not 

 measure the success of their expeditions by the weight of the 

 fish caught, so the amateur grower of flowers has other pleas- 

 ure in the cultivation of plants than in the mere magnitude of 

 the crop of flowers. A place in the warmest corner should 

 always be reserved for seed-pans, for until one grows seedlings, 

 and notes from day to day their development, he misses one 

 of the most interesting features of gardening. There is a 

 never-ending interest attached to the germination of seeds. 

 In the same corner, also, should be made a bed of sharp 

 sand, to be changed as required, where propagation of all kinds 

 may be carried on. If a frame be made over this, on which 

 a plant may be temporarily placed, it will often be useful in 

 grafting or in other cases where a close atmosphere is 

 required. Of course, this bed should have a bottom of slate 

 or zinc, and it is well to box in the space under the bench at 

 this point to confine the heat. A sash house is considered a 

 rather crude structure, but I find it has one advantage, which 

 is that where a house is left without attention all day, it gives 

 a certain amount of desirable shading when, as often happens, 

 the sun becomes unexpectedly powerful, and the ventilators
